DOC Race T4 Front Facing SR20DET Turbo Manifold W/ MVR Gate Option

The DOC Race T4 Topmount Turbo manifold is for the more extreme setup looking for the potential limit of the vehicles engine. This manifold is capable of well over 1000hp and is designed for peak-power situations with the open merge collector. The DOC Topmount manifold can still be used for “streetable” vehicles, but is solely designed to make maximum horsepower and allow you to fit much larger frame turbo’s then our traditional T3 Center set manifold. D.O.C. still applies our elaborate porting process to complement maximum flow within ALL of our manifolds.
